摘要:

为了提高三相有源电力滤波器(APF)实时跟踪和补偿谐波的能力，基于状态反馈精确线性化理论提出了一种有源电力滤波器(APF)非线性滑模控制策略。为了提高APF系统的动态性能和跟踪能力，建立了APF系统的仿射非线性模型，设计了电流内环非线性控制策略，并采用线性二次型调节器(LQR)方法进行了控制参数整定；为了调节和稳定系统的直流电压，采用滑模控制(SMC)进行了电压外环设计；搭建了仿真和实验平台，实验结果表明，该方法具有较好的动态响应、稳态特性和鲁棒性。

Abstract:

In order to improve the ability of low-voltage distribution network active power filter(APF) to track and compensate harmonics in real-time,this paper presents a non-linear sliding mode control strategy for APF.In order to improve the dynamic performance and steady-state performance of the system,the APF affine nonlinear model is established based on the state feedback precise linearization theory. A nonlinear control strategy for the inner current loop is designed, and the control parameters are set by using the linear quadratic regulator(LQR) method.In order to regulate and stabilize the system’s DC voltage,the outer voltage loop is designed by using sliding mode(SMC). Experiments results and indicate that the proposed method have better dynamic response performance,steady-state characteristics and robustness.
